Describe the transformation from f(x) to -3f (x + 1) 3. Of(x) is reflected over the x axis, stretched vertically by a factor of 3, shifted left 1 and down 3. Of(x) is reflected over the y axis, stretched vertically by a factor of 3, shifted left 1 and down 3. Of(x) is reflected over the x axis, stretched vertically by a factor of 3, shifted right 1 and down 3. Of(x) is reflected over the y axis, stretched vertically by a factor of 3, shifted left 1 and up 3.
